JOPLIN, Mo. (AP) — A woman whose husband and two children were among eight people killed while taking cover in a Home Depot during the 2011 Joplin tornado contends in a wrongful death lawsuit that the building was negligently constructed.

Edie Howard Housel, who lost her husband, Russell Howard, and their two children, 5-year-old Harli Jace and 19-month-old Hayze Cole, during the storm, specifically cites the 100,000-pound concrete slabs that made up the store’s walls. All but 10 of the 73 tilt-up panels fell after the tornado ripped the roof off of the building, including some that fell inward and killed Housel’s family members and others.
